Description

Technical Field

[0001] The utility model belongs to the technical field of cargo box locks, and more specifically, relates to a cargo box lock structure and a vehicle. Background Art

[0002] The side door locks of traditional tipping dump trucks, semi-trailers or full trailers generally adopt the manual opening method. Since the cargo carried by the cargo box has a certain thrust on the side door, it is often very laborious to open the side door lock. The operator needs to use a hammer to knock before the side door can be opened.

[0003] Taking a 13-meter tipping semi-trailer as an example, 18 locks need to be knocked open each time when unloading. Therefore, the above process takes a certain amount of time and physical strength of the operator. In addition, since the distance between the person and the car door is relatively close when opening the side door lock, when the side door is opened after the lock is opened, it will cause the concentrated scattering of the cargo. If the operator fails to dodge in time, it is very easy to cause injury, which has a certain degree of danger. Summary of the Utility Model

[0026] Compared with the prior art, for the structure of the cargo box lock provided in this embodiment, the locking claw 3 can rotate along with the mounting shaft 2 to achieve the clamping cooperation with the locking base 1, so as to realize the locking effect on the side door 61. The telescopic driving member 4 can drive the mounting shaft 2 and the locking claw 3 to rotate synchronously, and then separate the locking claw 3 from the locking base 1, so as to open the side door 61 to unload the goods. The above structure can drive the mounting shaft 2 through the telescopic driving member 4, so that the side door 61 can swing vertically around the upper rotating shaft 68 to facilitate the opening of the side door 61, without manual operation, shortening the opening time of the side door 61 and improving the convenience and safety of the operation.

[0027] In this embodiment, a side door frame 67 for installing the side door 61 is provided on the side of the cargo box 62. The upper edge of the side door 61 is rotatably connected to the inner top of the side door frame 67 through a rotating shaft 68. A locking base 1 is provided at the lower part of the side door 61. The locking base 1 is used for clamping with the locking claw 3 to ensure the closed state of the side door 61.
